+Open protocol defined by [IEC 62386](https://www.dali-alliance.org/standards/IEC62386.html).
+
+Includes wired (via [[twisted-pair-cable]] and 8P8C "RJ-45" connectors)
+and wireless topologies.
+
+##### Proprietary DALI Clones
+
+There exist several proprietary control ecosystems
+with feature sets and topologies identical to DALI.

+> I suspect these exist to skirt the cost of DALI's testing requirements.

+I'm less sure this is an apt description.
+The examples below are typical of some generic system,
